The purpose of this device is to give students or hobbyists the possibility to connect a high resolution wideband oxygen (O2) sensor to their projects or assignments. Adding accurate data, such as the oxygen content in a closed loop control environment will help students or hobbyists to develop more efficient and environmentally friendly combustion based solutions.
